5) Human recessive disease: cystic fibrosis Jane and John are expecting a baby know that they are both carriers (i.e., heterozygous) of cystic fibrosis (Cc). What is the probability that their child will have cystic fibrosis (CC)? What is the probability that their child will be a carrier of cystic fibrosis? Chance of child being: 25 % Homozygous dominant Genotype: 50_%Cystic fibrosis carrier Genotype: 25 % Cystic fibrosis Genotype: 6) Human recessive disease: Phenylketonuria A couple has just found out...

Follow-Up Questions 1. Your brother has an autosomal recessive disorder, while you are unaffected. Neither one of your parents is affected. Explain how this is possible. 2. Using the above situation, what is the probability that you carry the recessive allele? 3. A couple wants to have a child, but the mother has a brother who is affected by cystic fibrosis. They seek out the advice of a genetic counselor at their local hospital to determine what, if any, chance...

Cathy is pregnant for the second time. Her first child Donald, has Cystic fibrosis (CF). Cathy has two brothers Charles and Colin and a sister Cindy. Charles is married to an unrelated woman, Carolyn, and has a 2-year- old daughter, Debbie. Cathy’s parents are Bob and Betty. Betty’s sister Barbara is the mother of Cathy’s husband, Calvin. There is no previous family history of Cystic fibrosis. What is the pattern of transmission of Cystic Fibrosis? What is the risk for...

Sheree is referred to a genetic counselor because a cystic fibrosis (CF) test done as a routine part of her prenatal care indicated that she is a carrier of the most common mutant allele. Sheree is stunned, because no one in her family has the disease. She is 26 years old. The genetic counselor would most likely Multiple Choice o explain autosomal recessive inheritance and suggest that Sheree's husband be tested for CF. O explain autosomal dominant Inheritance and suggest...

sean and michelle are healthy, but their daugher molly was recently diagnosed with cystic fibrosis. Guess the genotype of the parents for cystic fibrosis disease? a. sean and michele are heterozygous for cystic fibrosis allele, they are carreirs b. sean and michele are homozygous for cystic fibrosis allele, but the disease will be manifested later in their life c. sean does not have the cystic fibrosis allele, he is homozygous for the healthy variant of the gene, michell is the...

You must try to answer both questions: Cystic fibrosis (CF) is an inherited disorder that causes severe damage to the lungs, the digestive system and other organs within the body. CF affects cells that produce thin and slippery mucus and cause the secretions to become sticky and thick. CF is caused by a deletion mutation on chromosome 7. In order for a child to have cystic fibrosis they must inherit a defective gene from each of his/her parents a) Rob...

Cystic fibrosis is a lung disorder that often results in death. It is inherited but can be inherited only if both parents are carriers of an abnormal gene. In 1989, the CF gene that is abnormal in carriers of cystic fibrosis was identified. The probability that a randomly chosen person of European ancestry carries an abnormal CF gene is 1/25. (The probability is less in other ethnic groups.) The CF20m test detects most but not all mutations of the CF...
Joan is phenotypically normal, but had a child with the autosomal recessive disease cystic fibrosis (CF)...
Joan is phenotypically normal, but had a child with the autosomal recessive disease cystic fibrosis (CF) from a previous marriage. Joan's father has hemophila A, a sex-linked recessive condition where the blood fails to clot properly. Her father has survived due to recent treatment advances. Joan now intends to marry Bill, who is also phenotypically normal but who has a sister, Jill, with CF. Bill's parents are phenotypically normal, and there is no history of hemophilia A in his family....

Parents who do not have cystic fibrosis (recessive) produce a child who has cystic fibrosis. What are the chances that each child born to this couple will have cystic fibrosis? 100% 75% 25% 0% All of the choices are correct. Could a man with blood type A father a child with blood type B? No, only males with type B or AB can have children with type B blood. Yes, if his genotype was AO and the mother had type...

3. Cystic fibrosis (CF) is an autosomal recessive disorder (cc) and is one of the most common life-shortening genetic diseases. In the United States, 1 in 4,000 children are born with CF. Symptoms of cystic fibrous include the production of salty sweat and thickened mucus in the lining of the lungs and air passages. The thickened mucus obstructs airways and promotes the growth of disease-causing bacteria in the lungs. Most individuals with cystic fibrous die in their 20s and 30s...
